Title: Spinning artificial filaments
IPC: D01D5/092
Filed: 1965-09-08
Abstract: 1,079,986. Spinning apparatus. FIBER INDUSTRIES Inc. Sept. 8, 1965 [Sept. 22, 1964], No. 38340/65. Heading B5B. A-process for the production of multifilament yarns comprises meltspinning a synthetic linear filament forming polymer through a multiorifice spinneret successively into an insulating zone extending from 2 to 20 inches in depth from the spinneret in which the freshly formed filaments are insulated from the ambient atmosphere and are divided into separate portions, and a cooling zone in which the divided filaments are cooled without turbulence by contact with a gas and collecting the divided portions as separate yarns. The cooling gas, suitably air at room temperature or other inert gas, e.g. nitrogen or carbon dioxide, is preferably supplied at a rate between 5 and 25 cubic feet per minute. Desirably the gas flow is substantially at right-angles to the filaments. Where the filament denier is from 1 to 10 the insulating zone is suitable from 2 to 12 inches in depth. The arrangement of the orifices, preferably 10 to 1000, in the spinneret is not critical and they may be arranged, for example, or parallel rows, crescent, semi-circular or circular formations convenient for dividing the thread lines. Synthetic linear polymers which may be used in the process of the invention, include polyesters, especially polyethylene terephthalate, co-polyesters, polyamides, especially polyhexamethylene adipamide, co-polyamides, and polyolefins, especially isotactic polypropylene and co-polyolefins. Apparatus, as shown, comprises a chamber 9 including an insulating zone 12 encircling a multi-orifice spinneret plate 11 and extending from 2 to 20 inches in depth from the plate for insulating from the ambient atmosphere freshly formed filaments which are melt-spun from melt-supply container 10 through plate 11 into the chamber 9 and a cooling zone extending beyond the insulating zone which is furnished with means for introducing cooling gas into the chamber in contact with filaments (cooling gas supplied via 15 passing from rotometer 18 into air chamber 17, and thence via diffuser 14) and means for dividing freshly formed filaments 13 into at least two separate portions in the insulating zone and collecting the cooled filaments into separate yarns. As shown, chamber 9 is suitably substantially cylindrical and fitted at one end with multi-orifice spinneret plate 11 and a peripheral porous wall 14 adjacent its opposite end. The porous wall may be constructed of sintered steel, sintered bronze, porous earthenware or perforated metal sheet or tube. After cooling, the. individual separated filament bundles 13 may be contacted with a suitable textile surface finish, if desired, and collected, e.g. on a bobbin or roller, or immediately forwarded to other processing steps. The process of the invention enables the extruded filaments to be divided into a number of portions, each of which is collected separately, while variation in filament denier is maintained within acceptable limits.

Title: Method and system for controlling a pipeline pump station
IPC: F04D15/00
Filed: 1960-11-18
Abstract: 906,329. Automatic control of pumping stations. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Nov. 18, 1960 [Nov. 20, 1959], No. 39715/60. Class 38 (4). In an automatic control system for a pipe line pumping station having a plurality of pump units of different sizes, the power level, defined as the number of pump units required to maintain the desired flow rate, is maintained constant by controlling the number of pump units operating in dependence on the hydraulic pressures in the pipe-line. As shown, a pumping station comprises pumps 10-13 connected across non-return valves 14-17 in a delivery line 20. A throttle valve 24 is positioned by a controller 22 responsive to the outputs of transducers 21, 23 sensing the inlet and delivery pressures of the pump station so as to maintain the pressures in the pipe-line within the desired minimum suction pressure and maximum delivery pressure. The output of a transducer 25, sensing inlet pressure, through an amplifier 30 is fed to a comparing circuit 33 which delivers an output when the suction pressure exceeds a minimum required value. The output of a transducer 26, sensing discharge pressure, through an amplifier 31 is fed to a comparing circuit 34 which delivers an output when the discharge pressure is below a maximum required value. The comparing circuits are connected to a logic " and " circuit 36 having an output to a logic circuit 40 when receiving signals from both comparing circuits. The logic circuit 40 receives a signal from a set power level circuit 45 which it compares with an operating power level signal from a switchgear 41 for the pumps. When the operating power level is below the set power level, the logic circuit supplies a signal to the switch gear 41, to cause an additional pump to be started, provided there is a signal from the logic circuit 36 indicating that the suction and delivery pressures are within the required values. The output of a transducer 27 is compared with that of the transducer 26 at the input of an amplifier 32, the output of which is fed to a comparator 35 which is connected to the logic circuit 40 so that when the throttle pressure exceeds a value representative of 75% of the capacity of the smallest pump, that pump closes down or at a value of 40% the smallest pump closes down after a time delay. The circuit 45 is controlled locally through a line 52 and remotely through a circuit 44 and line 43. The set power level is read by a circuit 46 connected to an indicating panel 53 and the operating level is read through a circuit 51 connected to the panel 53.
